Answer 1

In my case, I was getting the same "java.lang.NoSuchMethodError" deploying an EAR file to JBoss EAP 5.2.

The logs showed:

SLF4J: The requested version 1.5.6 by your slf4j binding is not compatible with [1.6]

Logs: (server.log)

Problem:

The problem was having two different versions of slf4j-api jars on the classpath. (slf4j-log4j12-1.5.6.jar, slf4j-api-1.6.1.jar)

Resolution:

1. I ran "mvn dependency:tree" to find the location of the transitive dependency.
2. Then, I added a maven exclusion tag to exclude the undesired artifact version.

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>1.5.6</version>
  <exclusions>
    <exclusion>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
    </exclusion>
  </exclusions>
</dependency>

Answer 2

Looks like you have a version mis-match between the various SLF4J API and integration libraries. SLF4J is extremely twitchy when it comes to version compatibility (e.g. 1.6.x is not backwards compatible with 1.5.x).

Make sure the various JAR versions match, and make sure there are no duplicate JARs on the classpath.
